Only Tang I ever had that would actively try to slice my arm with it's tail scalpel was a Sohal I kept many years ago (and NEVER will again). But, lately, my Sailfin has been trying to do the same thing. Perhaps not with quite the same maniacal glee that the Sohal exhibited, but trying none-the-less. Sailfin is on the larger side, probably 7" give or take, but it took me by surprise. Anyone else have a similar experience?
